IMPROVEMENT IN INKSTANDS.

Specication forming part of Letters Patent No. 144,825, dated November25, 1873; application filed i August 11, 1873.

represents a longitudinal section of an'inkstand embodying my invention.Fig. II is a cross-section at line .fr Fig. I, with some modifications.

A represents the reservoir, with the usual neck B. D is a funnelattached to the top of the neck B, and extending into the vessel towithin a short distance of the bottom. In the bottom of this funnel D asmall hole, a, is made. The funnel D may be made to form one piece withthe top part of the neck B, as shown in Fig. I, or the same may be madeseparate and ground and fitted air-tight into a suitable hole made inthe top part of the neck B, as shown in Fig. II. The reservoir A beinglled either through the funnel D or through a suitable opening made inany desired part, and afterward closed up air-tight, the ink will standin the neck B on a line level with the internal projection fw, and whichsaid level will be in the funnel D, as the ink can pass freely into thesame through the opening a. The bottom hole a being made small, the pencannot p ass through the same, and can only take up the clear iiuid inkcontained 'in the bottom of the funnel D, while the thick part orsediment of the ink will remain in the bottom of the inkstand and cannotget to the pen. On the top of the funnel D an internal iiange orprojection, lv, Fig. II, may be made to prevent the ink iiowing out whenthe inkstand is tipped forward to increase the level of the ink in thefimnel.

I do not claim a barometer-inkstand, provided with a wholly or partlyflexible air-tight funnel in the neck thereof, and the inkstand soconnected to a screw as to be raised and lowered thereby to cause theink to flow into the funnel; nor do I claim a barometer-inkstandprovided with a exible air-tight funnel in its neck, and so constructedthat a vent must be opened on the top of the reservoir to cause the inkto ow into the funnel, as I am aware that such are not new, but arefully shown in Figs. 22 and 23 of English Patent No. 580 of 1854. In myinvention the funnel is provided with a suitable vent or vents in oraround its sides. When the funnel is in position, as shown in Fig. I,the level of the ink in the neck and in the funnel are, of course, atall times equal, and no mechanical means are employed to accomplish thisresult, suchas the tilting of the inkstandor opening of vents or valves,as in the cases above referred to.

I claimy The barometer-inkstand A B, provided with the removableperforated or slotted funnel D, contracted to a point, having a smallope11- ing therein and in the neck B, so that the ink in the neck andthe ink in the funnel will be on the same level without the employmentof me chanical agencies, as set forth.
